When the frame rate is 25p or 50p (1080 50i-compatible device):
00:00:00:00 - 23:59:59:24
When the frame rate is 24p, you can set the last 2 digits of the time code between 0 and 23 in
multiples of 4.
To reset the time code

To select the recording method of the time code (TC Format)
- [Setup] - [
DF: Records the time code compensating gaps that arise between the actual time. (Drop
frame* method)
NDF: Records the time code without compensating gaps that arise between the actual
time. (Non-drop frame method)
*
When the frame rate is set to 30p or 60p for the NTSC TV color system, the time code is based on 30
or 60 frames per second. However, gaps in the actual time occur during extended periods of recording
as the actual frame frequency of the NTSC image signal is 29.97 frames per second. Drop frame
corrects this gap to make the time code and actual time equal. In drop frame, the first 2 frame numbers
(for 30p, 4 frame numbers for 60p) are removed every minute except in every tenth minute. The time
code without this correction is called non-drop frame.
To select how the time code advances (TC Run)
- [Setup] - [
Rec Run: Advances the time code during movie recording. Select this setting to record
the time code sequentially from the last time code of the previous recording.
Even if the time code advances in [Rec Run] mode, the time code may not be recorded
sequentially when the recording media is removed.
Free Run: Advances the time code regardless of the operation of the camcorder.
